Remnants of a formerly more extensive deposit composed of dry ice form what is known as the south polar residual cap. Scientists … High resolution images taken with NASA's Mars Global Surveyor show that the northern polar cap is covered mainly by pits, cracks, small bumps and knobs that give it a cottage cheese look. The pits are spaced close together relative to the very different depressions in the south polar cap. Visa mer The planet Mars has two permanent polar ice caps. During a pole's winter, it lies in continuous darkness, chilling the surface and causing the deposition of 25–30% of the atmosphere into slabs of CO2 ice (dry ice). … Visa mer Both polar caps show layered features, called polar-layered deposits, that result from seasonal ablation and accumulation of ice together with dust from Martian dust storms.

WebbThe Martian polar caps were first noted by the Italian-born French astronomer Gian Domenico Cassini about 1666. Visual observers subsequently made many key discoveries. The rotation period of the planet was discovered by Huygens in 1659 and measured by Cassini in 1666 to be 24 hours 40 minutes—in error by only 3 minutes.
